RE-POST: tomcat log error ?
Hi,
On a production application (Tomcat 4.1.18/JDK-1.4.1_01) we have an
intermittant error which leaves Tomcat in a state where it does not serve
our homepage or anything else (bouncing Tomcat fixes the problem). The
Tomcat log contains
the following error below. It looks to me like there is a problem accessing
a Tomcat log file but I am just guessing. The error appears in the
4teus_log.txt - as defined:
<Host name="localhost" debug="0" appBase="webapps" unpackWARs="true"
autoDeploy="true">
<Valve className="org.apache.catalina.valves.AccessLogValve"
directory="logs" prefix="4teus_access_log." suffix=".txt"
pattern="common"/>
<Logger className="org.apache.catalina.logger.FileLogger"
directory="logs" prefix="4teus_log." suffix=".txt"
timestamp="true"/>
<!-- Tomcat Root Context -->
<Context path="" docBase="" debug="0"/>
</Host>
Has anybody seen this before or can point me in the right direction to solve
this.
many thanks
Dan
